no you can't use mikes morphs on the p4 mike, but if you morph mike a lot your going to have to morph the p4 shirt to match not only mike but the morphed version of him..do you have a 3d app you could do this in, you can't really just create morphs for the shirt though coz the joints are all different, you'd need to reshape it and recut the joints...are you just needing a tucked in tee for mike coz i can send you one if you want..Steve
